    As Greywater Diverter:

    With the cost of water constantly rising and water restrictions in place in many parts of the world, it makes sense not to throw out the water that has been paid for and to reuse it to irrigate the household garden and trees. Today the G-flow greywater system is widely used to filter and pump laundry, shower and basin water into irrigation systems for gardens. The greywater system was originally designed for this specific application and carries the appropriate health and plumbing standards and certifications in countries such as USA, Canada, Australia, New Zealand & South Africa. Over 10,000 G-Flow Greywater diverter systems have been sold worldwide with remarkable plants and landscape outcome, as well as great water-saving results (as much as 200,000 Liters or 50,000 Gallons per household per year). In addition, this greywater system has won several water-saving awards in shows worldwide. Although most of the detergents today are biodegradable and environmentally friendly the use of low phosphorus and low salt detergents are recommended for improved long-term results.

    As Drainage Pump Sump station:

    Where part of the house or garden is flooded due to inadequate drainage, the G-flow has also been used as a pump station to shift the excess water out of the flooded area. The G-Flow incorporates the below-ground housing as well as the drainage sump pump and can be buried up to its lid cover, thus making it an economical, aesthetic, and handy little automatic pump station. The pump automatically activated by a float switch when the water level in the tank reaches a predetermined level.

    As Rainwater diverter:

    In many places around the world, rainwater is captured from roof areas and stored in large rainwater tanks for use in and out of the house at a later stage. The larger the roof catchment area the more water can be captured and stored especially during short summer rainfall events. The G-Flow has been used when building configurations do not allow part or all of the roof area to drain by gravity into the main storage tank. The G-flow has also been successfully used to capture and transfer the water originating from a nearby shed or garage roof area back into the main rainwater tank positioned further away.
